• Most kidney injuries can be managed conservatively, but, when definite indications for surgical intervention exist, efforts should be directed toward conservation of renal tissue. The clinical findings in a patient with renal injury vary with the amount of bleeding and urinary extravasation, but, when such damage is suspected, radiologic examination must be undertaken as soon as the shock-like state is adequately stabilized.
